Green-blooded humans existed and it turns out there are also several types of green-blooded animals such as frogs types of Cambodia and insects. This animal green blood because the blood does not work because it does not require oxygen carrying hemoglobin. Green colored blood in the medical world can indeed happen and in the medical world it is known as sulfhemoglobinaemia (SulfHb) which is derived from the color of hemoglobin and difficult to return to normal. People bleed green discovered in June 2007 by a team of anesthetists Dr. Stephan Schwarz, Dr. Giuseppe Del Vicario and Dr. Alana Flexman in Canada. At that time the doctors in the team is currently conducting operations in hospitals Vancouver St. Paul against a 42-year-old man who admitted to hospital because of a fall. The doctor was very surprised when the first incision in the patient’s leg, issued his blood is the blood that are dark green instead of red like a normal human.
green blood in humans showed that there is something abnormal occurs in the human body, so it tends to be a disease. If patients with very severe or extreme sulfHB it needed a blood transfusion to save the patient. Symptoms of excessive levels of sulfHB is evident from the changes in skin color and sulfur membranes that become bluish. This phenomenon is called cyanosis in the medical world. This condition is caused by lack of oxygen levels in the blood. Usually starts bluish color of the nails hands and feet, lips and tongue.
The main cause of sulfHB is the consumption of drugs such as acetanilid, phenacetin, nitrates, trinitotoluene and sulfur compounds (including sulfonamides) is excessive. Other causes could also be because there is exposure to sulfur compounds in the workplace or from environment contaminated by pollutants sulfur that occurs continuously so that the sulfur from the air we breathe into our bodies. As a result, when hydrogen sulfide (H2S or sulfide ion) and iron ions combine in the blood, blood is unable to carry oxygen.
Tentusaja green blood is not good for the body because they interfere with the functioning of organs especially the blood circulation in the body that require blood that binds with oxygen.
